That would be my take as well, and/or depending on the age of the piece
there could be a judicious screw or two w/ an elongated hole. That would
make it pretty recent, however, but age of piece wasn't mentioned.

Anyway, as long as the divider long grain doesn't try to restrict the
joint the whole length, not likely a problem. (If there were going to be,
one would presume the original piece would be showing the effects... ).

I have ripped 3/4 plywood in 2.5" strips and mitered the corners for the
dust dividers in a couple of projects. But not because I knew it to be a
sure-fire method. It was along a theory (hope and a prayer) that plywood's
inherent stability would all but eliminate expansion and contraction issues
for those components. And, although the side pieces were also plywood
(biscuited and glued!) I would like to hear a consensus as to whether the
same construction method would accommodate solid wood sides.
